YES. Because it is now the combination of 2 phases.
Heterogeneous
Pyrite is made of iron and sulfur and is the compound iron sulfide with the chemical formula FeS2. It is not a mixture of iron and sulfur. The iron and sulfur are chemically combined to form a compound.
it is heterogenous
wiggily?
Well, if we mix iron sulfur mixture and hydrochlonic acid, only the iron reacts.
Heterogeneous
No, the mixture of powdered sulfur and iron filling are not a homogenous mixture, they are a heterogenous mixture.
Sulfur is not a mixture at all. It is a pure substance. Specifically it is an element.
Sulfur is an element.
No, Iron is a homogeneous mixture as long as the iron is pure
Sulfur and iron filings together are a mixture.
Pyrite is made of iron and sulfur and is the compound iron sulfide with the chemical formula FeS2. It is not a mixture of iron and sulfur. The iron and sulfur are chemically combined to form a compound.
it is heterogenous
Iron ore is a heterogeneous mixture.
Reacting iron with sulfur an iron sulfide is formed, not a mixture.
